Experimental demonstration of spinor slow light

Abstract

Slow light based on the effect of electromagnetically induced transparency is of great interest due to its applications in low-light-level nonlinear optics and quantum information manipulation. The previous experiments all dealt with the single-component slow light. Here we report the experimental demonstration of two-component or spinor slow light using a double tripod atom-light coupling scheme. The scheme involves three atomic ground states coupled to two excited states by six light fields. The oscillation due to the interaction between the two components was observed. Based on the stored light, our data showed that the double tripod scheme behaves like the two outcomes of an interferometer enabling precision measurements of frequency detuning. We experimentally demonstrated a possible application of the double tripod scheme as quantum memory/rotator for the two-color qubit. Our study also suggests that the spinor slow light is a better method than a widely-used scheme in the nonlinear frequency conversion.
